Quantitative Toxicological Risk Profiling of Carcinogenic Heavy Metal Contaminants in Agricultural Products: A Focused Geo- Environmental Study in Tanore Upazila, Rajshahi District, Bangladesh

This study evaluates the contamination of agricultural crops with carcinogenic heavy metals in Tanore Upazila, Rajshahi District which is a well-known area for its important contribution to agriculture production. This study explores six frequently consumed plants- Green chili, coriander seed, potato tubers Brinjal fruit (whole), Onion bulb and Turmeric rhizomes. With the growing worldwide apprehension about heavy metal accumulation in food crops, particularly within developing nations, this research purposes to estimate the cadmium (Cd), lead (Pb), arsenic (As) and chromium(Cr) levels of these plants and evaluate health risk. Raw samples were obtained from the local fields and then they underwent strict cleaning & preparation protocols to give accurate results in the analysis. This was followed by quantification of heavy metals concentration using Atomic Absorption Spectrophotometry (AAS). E.D.I., T.H.Q. and H.I. were calculated to assess non-carcinogenic health risks. The final obtained results are for green chili, E.D.I. and T.H.Q. are respectively 0.000199 and 0.1993 for Cd, 0.000665 and 2.2167 for As, 0.000183 and 0.0458 for Pb, 0.000120 and 0.040 for Cr and H.I. is 2.5018. For coriander, E.D.I. and T.H.Q. are respectively 0.000031 and 0.0314 for Cd, 0.000055 and 0.1834 for As, 0.000283 and 0.0707 for Pb, 0.000133 and 0.0443 for Cr and H.I. is 0.3298. For potato, E.D.I. and T.H.Q. are respectively 0.000010 and 0.0097 for Cd, 0.000017 and 0.0554 for As, 0.000012 and 0.0029 for Pb, 0.000015 and 0.0050 for Cr and H.I. is 0.0730. For brinjal, E.D.I. and T.H.Q. are respectively 0.000005 and 0.0097 for Cd, 0.000007 and 0.0246 for As, 0.000011 and 0.0029 for Pb, 0.000010 and 0.0033 for Cr and H.I. is 0.0360. For onion, E.D.I. and T.H.Q. are respectively 0.000036 and 0.0361 for Cd, 0.000032 and 0.1068 for As, 0.000242 and 0.0606 for Pb, 0.000116 and 0.0387 for Cr and H.I. is 0.2422. For turmeric, E.D.I. and T.H.Q. are respectively 0.000022 and 0.1392 for Cd, 0.000042 and 0.1392 for As, 0.000241 and 0.0603 for Pb, 0.000118 and 0.0393 for Cr and H.I. is 0.2608.
